I voted poly motor mounts and stock tranny mount. When I switched my motor mounts I didn't notice much of a difference in vibration, but when I added the poly trans mount the vibration in the steering wheel and in the seat was horrible. I ended up putting the stock tranny mount back on.

I have poly/poly but I'm going back to a stock trans mount, 1LE if I can find it. Too much vibration.

I'm having no luck finding one. I do still have my stock original and it's not torn, I may just do that.

I just got my poly mounts in for the engine. I'll be picking up a stock mount for the tranny at some point.

So do you guys think i should do the motor mounts then when i install my kooks? Would the stockers be fine you think or would the polys help the exhaust from hitting the floor.

On Spohn's site, they say if you use solid motor mounts that you should use a poly tranny mount. I'm wanting to get the solid motor mounts but want to see if anyone else is running this combo?

Are these the poly mounts people are buying?
I've looked through the sponsors and cant' find any poly, just solid.
If these Summit\Prothane ones are them, they're in the mail tomorrow.
My motors all wobbly.

I got mine from spedinc (ls1speed.com). While I can't say they exactly rushed them to me, I did receive them after about two weeks.

I've got a poly/poly setup. I decided against the solid motor mounts because I know in the future i'm gonna have to pull my tranny to have it rebuilt. I don't feel any significant vibrations after the install, so it just made the car drive better

I wouldn't do both solids if you drive it on the street. You'll want to have SOME flex in there

I'd either do solid motors/poly trans, or poly/poly. I went poly/poly and was happy with the results. No more engine/exhaust movement at idle!
